. Fig. 4 is an enlarge adapting the locking pin 13,- the inner end of the 56 to form a crank 10 which UNITED STATES PATENT OFFICE.

To all whom it may concern Be it known that I, WALTER P. MURPHY,-

out moving thepin lifting lever from "its.

abnormal position; and with this and minor objects, my invention consists. of the parts and combinationof after pointed out.

This'application contains matter divided out of'my applications, Serial No. 519,471 and Serial No. 602,664.

In the drawing, Figure 1 is 'an end view parts being broken away with my of a car, improved rigging in position; Fig. 2 is a similar, view showing the locking pin up and the locking pin lever in abnormal-position; Fig. 3 is a top (plan view of Fig. 1; detail View of the joint between the hand lever and the pin lever; Fig. 5 is .a'top plan view 'of another embodimentof my invention partly in section; and Fig. 6 is a side elevation of the same. I The reference numeral 1 indicates a car body of any approved construction, 2 the end sill and 3 brackets ofi a standard make secured to the end sill.

4 is the coupler head secured to the car. The handlever 5 is journaled in the brackets 3 and retained therein by means of the cotter pins 6. The outer end of the lever 5 is deflected downwardly inside the corner late 7 as at 8 to a point below the under ace of the end sill and thence outwardly toward the side of the car as at 9, thus forming a crank handle which may be operated either by the hand or foot of the trainmen to revolve the lever 5. The inner end of the lever 5 is bent outwardly 11 011 its outer end.

The locking pin lever 12 is of a dlameter its mner portion to pass through lever being bent to form a hook 14 to prevent the lever from becoming accidentally Specification of Letters Patent.

straight from its ,eye 15 to.its inner parts as will be herein has a closed eye' Patented June 16, 1914.

disengaged from the locking pin. outer end of the locking pin lever 12 is bent to'forrn an eye 15.which is adapted to engage the eye 11 of the hand lever as more clearlyshown' inFig. 4. In the emb0d1ment shown in Figs. 1, 2, 3 and 4, I bend the lever 12 downward as at 16, thus forming a seat in which one side of the eye l 1 is positioned when the lever is in the pos1t1on shown in Fig. 1; however, the lever 12 need not with this downward bend 16 but may be end as shown in Figs. 5 and 6.

In Figs. 5 and 6, the crank 10 of the hand lever is provided with an elongated eye formed by a return bend 17, the end of which is bent inward as at 18 against .one side of the crank 10, as shown in Fig. 5.

The locking pin lever The 12 is provided with a hook 14F0n its'inner end and with an eye 11*. on its outer end there being lugs or bosses 19 on each side of the eye 11 whlch constltute an extended seat 20, which is convex on itsside walls and concave on its bottom wall. The convex walls permit sidewise movements of the lever 12 but at thesame time prevent the lever from movlng too far toward the end'sill.

In'use, the locking pin 13 is raised from,

locked position by operating the crank on the outer end ofthe lever 5, thereby elevating the crank 10 which carries with it the locking in lever to the sition shown in Fig. 2. Ilhder the safety la ws, the crank 9 must be returned to. a point below the under face of the end sill. Aswill be seen the eye of the lifting pin lever engages the eye ofthe crank of the hand lever, which will ermit the crank to return to normal position after operating the pin lever with- .out moving the pin lifting lever from its abnormal position as shown in Fig. 2.

1;. A release rigging including a crank having a return bend at its inner end, the end of said bend being bent in againstthe crank toform ,a horizontally disposed eye, and a pin lifting lever having a vertically disposed eye at its outer end to engage said return bend and overlie the crank thereby forming a joint which will permit the cran to return to its normal position after operating the pin lever without moving the pin lifting lever 'from its abnormal position.

2. A release rigging includlng an elongated crank having a closed eye at its inner g end, and a lifting pin leverhaving an eye at its outer end to engage the eye of the crank, lugs extending from each side of the lower portion of the eye of the pin to form an extended bearing for the lever in the elongated eye of the crank; the joint between the two e es permitting the crank to return to norma position after operating the pin lever without moving the pin lever from its abnormal position.

3. A release rigging including a pin lifting-lever havin a closed eye at its outer end, lugs exten ing from each side of the lower portion of said eye and having convex inner walls constituting an extended bearing, and a crank having a return bend at its inner end, the end of which is bent in [against one .side of the crank to form an elongated eye on the side of the crank,'
